Description

Technical Field

[0001] This invention belongs to the field of pipe processing, specifically, it relates to a fixed-length sealing device for oxygen-free copper grooved pipes. Background Technology

[0002] Existing PTC heating elements typically consist of a PTC ceramic heating element and a metal outer sheath. PTC heating elements offer advantages such as low thermal resistance and high heat exchange efficiency, making them an automatic, temperature-controlled, and energy-saving electric heater. When manufacturing liquid PTC heating rods, it is often necessary to seal one end of the metal outer sheath.

[0003] Chinese Patent Publication No. CN202022033600.1 discloses a sealing device for high-frequency heated metal tubes, including a round tube feeding device, a high-frequency heating device, and a rolling device. One side of the front end of the round tube feeding device is equipped with a high-frequency heating device for heating the cut portion of the round tube, and the other side of the front end of the round tube feeding device is equipped with a rolling device for sealing the cut portion of the round tube. A grinding device is located at the front end of the round tube feeding device for grinding the sealed portion of the round tube. Below the grinding device are files, including a round tube surface file and a cut file. This invention provides an automatic sealing device for metal tube ends that offers high sealing efficiency, low welding stress at the sealing point, a smooth weld surface that is not prone to rust, and safe and stable operation.

[0004] After the sealing equipment for the metal pipes is completed, manual operation is required to loosen the copper pipe by unlocking the clamps, then push the copper pipe forward to a certain distance and clamp it again before sealing. The operation is cumbersome.

[0005] In view of this, the present invention is proposed. Summary of the Invention
